Beware of income-based limits on itemized deductions and personal exemptions

October 25, 2016

Share:

Many tax breaks are reduced or eliminated for higher-income taxpayers. Two of particular note are the itemized deduction reduction and the personal exemption phaseout.

Income thresholds

If your adjusted gross income (AGI) exceeds the applicable threshold, most of your itemized deductions will be reduced by 3% of the AGI amount that exceeds the threshold (not to exceed 80% of otherwise allowable deductions). For 2016, the thresholds are $259,400 (single), $285,350 (head of household), $311,300 (married filing jointly) and $155,650 (married filing separately). The limitation doesn’t apply to deductions for medical expenses, investment interest, or casualty, theft or wagering losses.

Exceeding the applicable AGI threshold also could cause your personal exemptions to be reduced or even eliminated. The personal exemption phaseout reduces exemptions by 2% for each $2,500 (or portion thereof) by which a taxpayer’s AGI exceeds the applicable threshold (2% for each $1,250 for married taxpayers filing separately).

The limits in action

These AGI-based limits can be very costly to high-income taxpayers. Consider this example:

Steve and Mary are married and have four dependent children. In 2016, they expect to have an AGI of $1 million and will be in the top tax bracket (39.6%). Without the AGI-based exemption phaseout, their $24,300 of personal exemptions ($4,050 × 6) would save them $9,623 in taxes ($24,300 × 39.6%). But because their personal exemptions are completely phased out, they’ll lose that tax benefit.

The AGI-based itemized deduction reduction can also be expensive. Steve and Mary could lose the benefit of as much as $20,661 [3% × ($1 million − $311,300)] of their itemized deductions that are subject to the reduction — at a tax cost as high as $8,182 ($20,661 × 39.6%).

These two AGI-based provisions combined could increase the couple’s tax by $17,805!

Year-end tips

If your AGI is close to the applicable threshold, AGI-reduction strategies — such as contributing to a retirement plan or Health Savings Account — may allow you to stay under it. If that’s not possible, consider the reduced tax benefit of the affected deductions before implementing strategies to accelerate deductible expenses into 2016. If you expect to be under the threshold in 2017, you may be better off deferring certain deductible expenses to next year.
